At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
I checked your form and only field that was selected by default is 'Caller is' and that's because it was set up to be selected, as you can see below:
You can just put first option, blank, for that one and it will not be selected by default.
Please let us know if you have further questions.
